Just ordered my test pipe and downpipe to go with my Greddy Ti-c catback. Can't wait to get them and on the car.

 

Of all of your test pipe and high-flow cat options, which one is the quietest? I want the power gains but don't want the increase in noise.

 

While we don't offer this as a guarantee, most of our customers do not receive a CEL.

Of all options, the ceramic high-flow cat is the quietest (also the most restrictive), next up would be the metal substrate high-flow cat.

Thanks! I don't plan on making huge power, just a few bolt-ons and a tune, so I'd prefer to sacrifice power for a quieter exhaust.

 

Any up dates for the O2 housing or not yet??? I am running out of time lol.

 

I just want to see the gains for this bad boy!

 

With regards to quietness with my test pipe installed with no options just the straight pipe it is barely louder than stock regardless of your speed/rpm. A little louder in car but just barely. 7k miles on my test pipe and no CEL yet.

 

Was the dual exit exhaust plan abandoned?

 

Not at all, guys. Being summer and all, we're just swamped here.

K, just asking.

 

Just got the Mini-Muffler test pipe and down pipe delivered before last weekend and the peices look great! Sadly I can't install them until my Buschur dual exhaust comes in, as they had an issue with a supply of exhaust tips delay the build... someone send them some tips!

 

Got my testpipe and downpipe in 5 business days! quick delivery and the pieces look fantastic! The fitment is excellent and I have no check engine lights at all.

I need some opinions though..... Once I put the testpipe, my car sounds waaayyy too loud. If I wanted to tame the beast, would you recommend a HFC? or a mini-muffler? I don't want to compromise too much power in the process...

Do those HFC's actually help with the db levels being so small in dimension?

thanks in advance!

 

Do you have a catback already? If not than I don't know what you're talking about because with just a test pipe and stock exhaust it's still incredibly quiet. If you do already have a catback though, then yes, adding a Mini Muffler would help or a silencer of some kind for the catback if it came with one.

 

They have lots of options and are great to work with, just give them a ring if you need additional advice, but the ultimate turbo back with the mini muffler testpipe is plenty quiet, not stock quiet but not obnoxious by any means.
